"When we think of #greenhousegas emissions, we tend to think of tailpipes and factories," said Scott Tiegs, co-author of the study and a professor of biological sciences at Oakland.
"But a lot of carbon dioxide and methane comes from aquatic #ecosystems. This process is natural. But when humans add nutrient #pollution like #fertilizer to fresh waters and elevate water temperatures, we increase the decomposition rates and direct more #CO2 into the atmosphere."
"A U.N. tribunal on maritime law said Tuesday that countries are legally required to reduce #GreenhouseGas pollution, delivering a long-awaited opinion sought by small island nations that are on the front lines of #ClimateChange.
The International Tribunal for the Law of the Sea found that carbon #emissions qualify as marine pollution and said countries must take steps to mitigate and adapt to their adverse effects."
From wooden buildings to air filters – how green cities could remove CO2 from the atmosphere
More than a thousand cities around the world now have #NetZero pledges: they want to emit only as much #CO2 into the atmosphere as they can simultaneously recapture.
Technically speaking, urban removals of this most important #GreenhouseGas could add up to one gigatonne (i.e. 1,000 million tonnes) per year by mid-century.
No matter which Republican gets in the oval office again, it's over. We will never have a vote again that means anything. It would be like Russia.
This shit is real, and on top of greed there are a lot of very wealthy people who want pardons for skeletons in closets.
Do you think anyone becomes a billionaire without skeletons to hide?
This #technology is still in its infancy and the biggest challenge will be how to effectively capture #CO2 - but it's hoped advances like this could slow the planet's rapid warming.
#Methane, the main ingredient in 'Natural Gas', makes up 16% of our total #greenhousegas emissions. 🐄 Here's everything you need to know about the 'Natural Gas': https://buff.ly/3HUaNqN
From today's local newspaper via Bay Area Newsgroup...
"The brand-new vehicles (buses), which could arrive as soon as the end of 2024, have water as their only tailpipe emissions....
There's just one problem: Most of the #hydrogen that is currently available is produced from #fossilfuels, and that causes more of the #greenhousegas emissions that hydrogen buses are supposed to reduce."
Amazing. TIL that @arte the franco-german public service broadcaster in Europe has a completely open app showing their programmes. Here to celebrate is a beautiful short documentary about Eunice Newton Foote, including a re-enactment of her (now famous) experiments showing how #CarbonDioxide is a #GreenhouseGas.
(TIL also that #UncleSam was actually a real person) #ClimateChange#eunicefoote#ArteTV
Where have all the cows gone? | Meat and dairy production accounts for 14.5% of global greenhouse gas emissions. How are newer farming methods impacting our environment? | Charlie Clutterbuck
The province is home to an abandoned gas well that leaks methane, an explosive #GreenhouseGas, into the atmosphere at the highest rate ever recorded in North America.
Countries have already suffered deep losses as a result of the #fires, #floods, and other disasters intensifying with #ClimateChange. They want the biggest, heaviest-polluting nations to do something about it. And they’ll be making their case at a conference presided over by an oil baron. #ClimateCrisis
The analysis led by Greenpeace estimated the Burrup Hub expansion could lead to 6.1bn tonnes of CO2 across the decades ahead if fully developed – roughly 13 times what #Australia emits annually."
"For the first time there will be a dedicated food day, and #food, #agriculture and #water will be the focus of at least 22 major events during the fortnight of #COP28 talks in Dubai.
For the first time, too, the FAO will outline how food systems must change for the world to stay within the globally agreed goal of limiting temperature rises to 1.5C above pre-industrial levels."
"Documents show industry intends to go ‘full force’ in arguing #meat is beneficial to the environment at #climate summit.
Meat and dairy companies are under increasing pressure over their large #GreenhouseGas footprints. The dairy industry is responsible for 3.4% of global human-induced #emissions, a higher share than aviation."
